W Specification of Letters Patent.

Application filed June 5, 1916. Serial N 0. 101,702.

Paint-Brushes; and I do hereby declare that" the followin isa full,clear, and exact description of t e same, reference being had to t eaccompanying drawings, and to the numerals of reference marked thereon,which form a part of this specification.

In applying paint, varnish, and the like y dipping a brush into a paintor varnish pail and then working the brush over the surface to bepainted, a considerable waste occurs due to the fact that in thetransfer of the brush from the pail to the surface being painted,quantities of paint drop from the brush, or are splashed therefrom whenthe brush is actuated. This not only causes a waste of paint butoftentimes cause damage to surfaces where it is not desired.

This invention relates to improvements in painting outfits in whichpaint is forced from a tank or reservoir by means of an air pump, thepaintbeing fed through the handle of a brush to the bristles thereofthrough a suitable rubber mouth piece or nozzle having. a restrictedopening with the mouth pieceproevenly supply paint in desired quantitieswithout waste or scatterin of the paint.

It is an object of this mvention to construct a painting outfit adaptedto evenly supply paint to, and through a brush from a reservoir-tank byair pressure.

It is also construct a an object of this invention to pressure fountainpaint brush,

adapted to receive paint through the brush handle and through arestricted opening in a flexible mouth piece disposed between'the brushbristles.

It is furthermore an object of this invention to construct a paintingoutfit comprising a paint receptacle having an air pum and a flexibleair cylinder associated therewith, adapted to force paint by' airpressure through a passaged brush and rubber mouth piece to the brushbristles.

It is finally an object of this ll'lVBIltlOIl' to construct a fountainipaint brush adapted to permit paint to be ed through the brush handleand through a rubber mouth piece on said handle, to the brush bristlesby air pressure.

The invention (in a preferred form) is. illustrated in the drawings, andhereinafter more fully described.

In the drawings:

As shown in the drawings:

The device comprises a framework or casing 1, made up ofmetal strips andangle irons. Pivotally mounted oneach side at the upper end of theframework is a ring or attaching loop 2, adapted to be engaged by anadjustable strap 3, for carrying or hanging up the device. Saidframework 1, has the angle irons disposed across the sides of its lowerend, as clearly shown in Fig. 3, and is open at its upper end to receivea paint can, tank or receptacle 4, therein resting on the horizontalflanges of said angle irons. The can 4, has a centrally disposed concaveportion 5, in its upper end, having an aperture therein in whlch issolderedor otherwise rigidly secured an outwardly threaded stub pipe ornipple 6, adapted to receive a coupllng nut 7, threaded thereon toconnect one end. of a pipe 8, to said can. The bottom of said can 4, isconvex and has a large circular central opening to the edges of which issoldered or otherwise rigidl secured an outwardly threaded downwardlyprojecting rim 9, for a purpose hereinafter described.

Rigidly and removably secured toone side of the framework 1, by means ofbrackets or metal straps 10, is an air receptacle or cylinder having acentrally apertured top plate 11, the outer edge of which is bentdownwardly to afford a circular flange 12. Rigidly secured in theaperture in said top plate 11 is an outwardly threaded nipple or stubpipe 13, to receive a coupling nut 14, to connect the pipe 8, with saidair receptacle. The bottom of said air receptacle comprises a base orbottom plate 15, the outer edge of which is bent upwardly to afford acircular flange 16. Secured to said circular flanges 12 and 16, in amanner to prevent air leakage, is, a rubber cylinder or tube 17. Formedor rigidly secured in the center of said base plate 15, and projectinginwardly into the to the lower end of an air pump comprising acylindrical casing 22, having a plunger head 23, and plunger rod 24,therein adapted to be moved upwardly and downwardly within said pumpcasing by means of a handle 25, on the upper end of the rod 24, to

pump air into the air receptacle. Said air pump is secured to one sideof the frame work 1, adjacent and parallel to the air receptacle bymeans of metal brackets or straps 26.

. Threaded onto the rim 9, of the paint can 4, is a cap 27, having avalve or sto cock 28, secured thereon to control the ow of paint fromthe can nected at one end to said valve 28, and having its other endconnected to a second valve or stop cock 30, secured to the upper end ofa handle 31, of a fountain paint brush. Said handle 31, has a centrallydisposed tube 32, extending therethrough, the upper end of which isconnected with the valve 30, and the lower end being open andterminating at the lower end of the handle. Connected to the tube 32, onopposite sides thereof and extending obliquely therefrom through thelower end of the handle 31, are auxiliary tubes 33,

i the lower ends of which are alined with the lower end of the tube 32.The lower end of the handle 31,is provided with a peripheral recess orgroove adapted to permit a mouth piece 34, made of rubber or othersuitable material to be secured to the handle as clearly shown in Fi ormouth parallel to the lower end of the handle opposite the lower openends .of the tubes 32 and 33. Also secured by any suitablemeans in thegroove at the lower-end of the handle and surrounding the mouth' piece,34, are brush bristles 35, of any required kind, the upper ends of whichare pressed together by a band 36 of anysuitable material secured aroundthe lower ortion of the handle to assist in holding t e bristles inposition.

The operation is as follows:

device as shown inFig. 1, maybe carried I by a painter or operator bymeans of the strap 3, which may be hung around the neck or over theshoulders of the operator. The

.through the I air 4, through a hose 29, congs. 5 and 6, with the tubes.32 and 33, commumcating with the interior" valves 28 and 30, are closedand the air pump is operated by actuating the plunger head 23, in thecasing 22, to pump air valve 18, into the air receptacle, the rubbercylinder 17, forming the sides thereof being adapted to stretch topermit the air receptacle to hold air under pressure, the valve 18,being automatically closed by theair pressure in the receptacle. Thevalves 28 and 30, may now be opened any desired amount. The air underpressure from the air receptacle flows upwardly through the pipe 8, intothe paint can 4, forcing the paint downwardly through the valves 28 and30, and the hose 29, through the tubes 32 and 33,'into the rubber mouthpiece 34, from which position the paint is forced evenly between the lis of the mouth piece thus saturating the rush bristles 35, with paint,which may now be applied tothe surface to be painted in the customarymanner. The amount 'of paint supplied to the brush is of coursecontrolled by the valves 28 and 30. i

It is evident from the drawings that the paint can 4, when empty may bereplaced by a full can of paint by simply removing the cap 27, and thepipe 8, and that the flow of paint through the lips of the mouth piece34, is dependent upon the air pressure in the air receptacle and theadjustment of the controlling valves 28 and 30. The flexibility andshape of the mouth piece 34, also-tends 1 tubes 32 and 33 from dryingout and clogging the brush.

I am aware that various details "of construction may be varied through awide range without departing from the principles of this invention, andI therefore do not purpose limitingthe patent granted otherwise thannecessitated by the prior art.

. I claim as my invention: 1. In a device of the class described thecombination of a portable paint can, with an air pump mounted to oneside thereof an elastic air cylinder mounted adjacent sai pump andconnected at its bottom with said P p brush paint can, controllingvalves therefor, and means in the bottom of said elastic air cylinderadapted to admit air under pressure from said pump into said cylinderto-force paint from said paint can through said I brush when thecontrolling valves are open.

2. In a device ofthe class described the combination .of a portableframe, a paint When it is desired to do any painting the can removablysupported therein, an air valves therefor, an air receptacle'connecteand at its top with said paint can, a connected with. the bottom oftheat its bottom 'with said-pump and at its top Valve in the bottom ofsaid receptacle adapt- 5-ed to admit air under perssure from said pumpinto said receptacle to force paint from said can through said brushwhen said controlling valves are open.

In testimony whereof I have hereunto STANLEY GASPARAITIS.
